中文摘要
目的分析安氏Ⅲ类错患者的头颅侧位形态特征及其与治疗的关系。方法收集北京大学口腔医院1997—2000年就诊的安氏Ⅲ类错患者472名，通过影像测量及最小平方和重叠法（PS）处理获得患者的标准化点坐标值并以此为统计指标对472例患者进行聚类分析和亚型分类，并总结各亚型的治疗方式。结果472例患者共分成14类亚型，通过计算机绘图形成了各亚型的图形模板，同一类亚型的治疗方式较一致。结论安氏Ⅲ类错具有不同的颅面骨骼分型，这些分型对于治疗方式的选择具有重要的意义。
英文摘要
Objective To analyze the morphological characters of Angle′s Class Ⅲ malocclusion patients and the relationship between characters and treatment options. Methods A total of 472 Class Ⅲ patients were collected during 1997 -2000. The standardized coordinates′ values of the patients were obtained by Procrustes superimposition（PS）. Cluster analysis was carried out to divide the patients into different subdivisions and the relationship between treatment options and subdivisions was analyzed. Results 472 patients were divided into 14 subdivisions with special characters. The morphological templates were formed by computer. There were certain relationships between characters and treatment options. Conclusion The mechanism of malocclusion of different Class Ⅲ patients are not necessarily same. The typing has significance to choose the treatment method.
